This inventlon relates to flanging machines, and more particularly to machines for forming at each end of a can bodythe flange which is to be intercurled with the flange of i the can top or-head to provide the wellof the operation of flanging an endless edge of a sheet-metal body, in which what is known in an ordinary sense as solid material must be made to flow under 'exteriorly applied and inherently acting tensile forces of such strength as to be destructive if applied too suddenly or abruptly, dicapped all efforts to increase therefore the capacity thetical. For thisand doubtless many'other,

reasons, the development of fla'nging machmes in the'can-maklng art, in-so-far as speed and capacity is concerned, has failed to keep pace with the development of body forming and heading machines.

Undoubtedly a die-flanging operation may be performed with reasonable certainty of success much more rapidly than a rollerflanging operation, and yet, on the other hand, it has been found practically impossible to die-flange a can body and produce a flange of approved or-desired configuration at one operation that is to say, in die-flanging a second operationis generally necessary to bend down to substantially rectangular position a sufficient portion of the body of the flange and sharpen the round corner be-g tween flange and body. The necessity for a second operation, as a rule, means a curtailment of 'capac1ty possibihties, and even in connection with roller-flanging it is apparent that in order to effect the same-result, the

operation must be prolonged, sothat the lat-- ter process is subject to the same objection; One of the principal objects of the present invention is the provision of a machine has undoubtedly hanthe speed and of fianging machines 'in' general, as the idea of attaining a high Q rLANeIne-Mieomnn which will not only receive, flange and eject a can body or can bodies with comparatively great rapidity, but one in which theflange Specification of Letters Patent, 7 Patented Oct. 2191?. r pplication filed.

is finished, as well'as formed, without loss of time. -More specifically, I have in view' a machine .by means of which I may avail myself of the capacity'possibilities of dieflanging without the usually attendant loss oftime and-energy heretofore required to re-shape the formed flange for the heading operation. W th the same ends in view, this taneously' flanging both ends of the can body, thus not only saving time but simplifying construction and operation by to a large 'exthereto'and ejectment of flanged bodies therefrom is limited only'by the duration of the flanging operation. Incidental to the above,-

I have in view general simplicity of construction and operation, economy of power and manual attendance and dependability 'of character of product.-

My invention will by reference to the accompanying drawings,

forming a part of this specification, in

which v Flgure 1 1s aslde elevatlonof a machine embodying my invention;

invention contemplates a machinefor SlIIllllr,

Fig. 2 is an end or front elevation thereof, 1

partly in section on the line 2-2 of- Fig, 1'; Fig. '3, is an enlarged partly sectional side elevation of one of-the fianging dies;

Fig. at is a central view of an unflanged can body;

Figs. 5 and 6 aresimilar views of the same under action of the Hanging dies and'the.

finishing dies, respectively.

Referring now to the drawings in detail, I have shown'a main supportin'gframe 11 which includes the legs 12 and upon which On the rear side of said frame is mounted the front tilted or inclined plate or table 13.

11 are provided brackets lt in which is journaled the main driving shaft 15 carrying the pulley 16 which has the usual connection with a suitable source of power, said pulley being preferably connectible to and disconnectible from said shaft through the inter-I position of any suitable form of clutch mechanism 17 operated by means of'a lever 18,

. so i be readily understood Y I I shafts 15 and 19, respectively.

' journaled near the lower end of said frame whereby the machine may be started and stopped at will.

In the upper end of the frame 11 is journaled the horizontal shaft 19, driven from the shaft 15 ireferabl T b means of a belt running over pulleys 21 and 22 on said 11' is journaledthe shaft and on the shafts 19 and 23 are mounted the sprocket wheels 24 and 25, respectively, of equal size, which carry the sprocket chain 26.

On the rear face of the tilted or inclined table 11 are mounted a plurality of journalboxes, including the boxes 2?, 28 and 29,- on

one side of the machine, as shown in Fig,

2, and their correspondingly located oounterparts on the opposite side of the machine. Referring first to these bearlngs on one side of the machine, as shown in Fig. 2, in each thereof is ournaled a short shaft, the shaft 30 being shown in the box or hearing 27, the shaft 31 i the box or bearing, 29, and thebox or bearing 28 being provided with a similar shaft, which does not appear in the drawings; On the shafts 30 and 31 are mounted the equal spur-gears 32 and 33, re-' spectively, each in mesh with a spur-pinion the pinion 3st and the gears 32 and 33, theshafts 30 and3l are rotated at the same velocity and in the same direction. Theopposite counterparts of the shafts 30 and 31 and their hearings, to which I have referred, are correspondingly rotated in the same manner, at the same velocity and in the same direction. I

The ends of the shafts 30and 31 project through the plate or table 13, and in front of said plate are provided with eccentrics 40 and 41, respectively. On these eccentrics are provided studs 1-2 and 453, respectively, upon which is journaled a frame which includes the three die holders 4%, a5 and 4:6.

" It will be seen, therefore, that upon rotation of the, shafts 30 and 31, this frame will be given bodily, movement in a circular orbit, and a corresponding framewhich includes the die holders 44, 4:5 and 46 being correspondingly mounted and similarly actuated on the other side of the macliine','it will be seen that these frames simultaneously appreach and recede from each other, and inapproaching each other'have corresponding movement at the same velocity toward the upper end of the machine.

The frame particularly described may be iou'r'naled upon the stud 42 in any common Suitably andwell known -manner, through the provision of a circular bearing and the interposit'ion'of suitable collars or gaskets, but in order to provide for unavoidable 1naccn be'no binding or unequal wear of parts due to slight variations in sizes and inaccuracies of adjustment, yet the path of movement of the driven frame duringpits useful stroke being positively determined and controlled.

In each of the die-holders f5. and 46 is mounted the-shank of one of the two flanging, dies 49 and 50,and correspondingly.lo-

cated and oppositelygoperating diesiSX and 50- have shanks mounted in the die holders 45 and 46 in the frame on the opposite side of the machine. These dies, therefore, are; counteracting, and each serves to support thework against the forces of operation of the other when canbodies to be flanged are interposed therebetween. In the die-holder 44: is mounted the shank 51 which is common to the two-straightening or finishing dies 52 and 53,- cooperating in a similar manner with the corresponding dies 52 and 53-, the shank'5l of which-is mounted in the die-holder44" of the frame on the other side of the machine.

The sprocket chain 26 is provided witha V series of carriers 54;, so shaped as to engage and convey initially cylindrical can bodies through the ".{ianging V mechanisms. These can bodies 55 maybe fed to this conveyor thlOUgh the medium of achute 56, so inclined as todeliver said can bodies succes sively to the conveyers 54% by gravity, each body beingengaged and retained in a .sub-

stantially horizontal position by one of said carriers, the latter being equidistantly spaced apart, and while traveling over the flat-front face of the plate or table 13 so spacingsaid bodies apart as to properly position the same for engagement by the flanging dies. In Fig. 2,- the two can bodies 55- are shown while the same are being sul jectc'd to the actions of the dies 49 and 50 and their opposite counterparts 49 and 50, while the can bodies 55 are shown in position where the straightening or finishing operations are being performed by the dies 52 and 53 and their opposite counterparts 52 and 53; The movement of the chain 26 is continuous and uniform, and the can bodies are consequently moving at a uniform velocity with said chainthroughout the fianging operations. Therefore, thevelocity ofthe revolving die-carrying frames is made, through their actuating connections;

ing and flange completing. operations, and I there'is no interruption of movement of any part of the machine. As hereinbefore' set dies e9, 5 0, 459 and 50 are identical in constructionand are similarly mounted and op-- erated. Therefore, a detailed description of one will suffice for all thereof. As shown] in Fig. .3, the carrier" L5 is provided with a cylindrical bore within which s seated the shank 57.0f thedie 49. Near the outer end ofthis bore isprovided the adjusting plug 58, which is rigidly held in thedesiredposition in said bore by means ofthe shank 59 of the clamping bolt 60. -Threaded through the plug 58 is the adjust'ing screw 61, against the endof which the end of the die-shank 57 abuts. By means of this screw 61, therefore, the relative location of the die 49 may be determined, and said die rigidly retained in this adjusted position by means of the shank 62 of a clamping bolt 63 engag-j ing the die-shank 57. 1 3 v The operating face of the die 49 prefer-' ably comprises the tapering face 63, adapt ed to first engage the end edge of the can body 55 and in operating properly position said body to a higher degree of exactness than would be possible with the carriersfi alone. The tapering face 63 terminates in a cylindrical portion which is of substantially the same diameter as theinternal diameter of the body 55, and this cylindrical pOr-I tion terniinatesin-an outwardlycurved portion which directs the endedge of the body 55 outwardly. to practically form the desired flange, a ring 64 being preferably provided to prevent over-fianging and to insure a substantially circular flange end;

In thus positively determining and con trolling the flow of the metal in the formation of this flange, it will be apparent that the inherent resiliency of the metal oper-f ated upon will tend to bind a can body upon;

the die and interfere with ready dislodgment of said body from the dies when the" H latter are moved away from each other. To overcome the fr ctiondue to these forces, l. have shown the die-head dividedvinto two parts, a rigid part 41:9, anda part 5 pivoted to said rigid part near the edge thereof and having a limited pivotal move ment with respect thereto. Suitable sockets are provided in the contiguous faces of these parts for the interposition. a' com-. pression spring 66 therebetween,sa dsprmg yielding readily to the forces of the fiangin-g forth, the -hanging binding tinuous procession through the machine,-of

configuration best adapted to receive the flanged top and be intercurled therewith by the usual double-seaming operation.

fter this finishingop'er-ation, the flanged can bodies continue their upward movement progressively with'the carriers 54;, to be finally discharged upon a suitable chute 67, which directs them under action of gram, ity to a heading machine or to any other ul-' timate point of delivery.

From the foregoing it will beseen that I have provided a fianging machine whichmaybe practically and successively operated at great speed; which will simultaneously flange both ends of a can body in transit withoutinterruption of advancing movement; which, while employing die-fianging mechanism that requires two operations for completion of the flange, so performs these operations that there is no loss of time, as p the second operation is completed by the finishing dies while the first operation is be- I ing completed by the fianging dies; which is comparatively simple in construction, due to .making' they work self-supporting by simultaneously flanging both ends of the can .body, and for -many'other reasons; which is simple and dependable in opera tion, comparatively light in weight, and

tendance; l

Many modifications of minor details of my improved fianging machine will doubtless readily suggest themselves to those skilled in the art to which it appertains, and I therefore do not desire to limit my invention to; the specific construction herein shown and described.
